Final answer:
The not a component of Mendel's five-element is not listed in the given options.
Step-by-step explanation:
Mendel's five-element includes alleles, dominant, recessive, and gene. Therefore, the correct answer is none of the above options. Mendel's postulates describe the inheritance of characteristics through pairs of alleles that behave in a dominant and recessive pattern. These alleles segregate into gametes and genes assort into gametes independently of one another. Additionally, Mendel's experiments with pea plants suggested that the presence of the dominant allele hides the recessive allele and makes no contribution to the phenotype.
